The later inquest in Jamaica was unable to determine what caused the Pakistan coach's death.

Despite the tragic turn of events from eight years ago, experienced batsman Younis played down any revenge aspect to Sunday's crucial Pool B game where the loser will be in severe danger of exiting from the World Cup.

"There is no element of us trying to avenge the 2007 defeat," added the 37-year-old batsman ahead of Sunday's game in Adelaide.

"Ireland are a side capable of causing an upset. So we are going to take this match very seriously."

Pakistan will go into the game buoyed by their surprise victory over South Africa which reignited their campaign after the earlier heavy defeats by India and the West Indies.

"The win over South Africa has given us a big boost and we are hopeful now that we have the capability of playing in the semi-final and final," Younis said.
